10R-1273 Ca-terpillar C15/C15 ACERT/C18 Reman Fuel Injector (EUI) – Replaces 249-0709 239-4909

This electronic unit injector (EUI) is a direct, OEM-equivalent replacement for Ca-terpillar C15, C15 ACERT and C18 diesel engines. Cross-referenced against OEM part numbers 235-1400, 235-1401, 244-7715, 244-7716, 249-0702, 249-0709 and remanufactured numbers 10R-1273, 10R-9236, 10R-3261, it is a true bolt-on fit with no core required.

Each unit is flow-matched and 100% bench-tested for injection pressure, spray pattern and delivery volume — delivering consistent firing, faster cold starts, better fuel economy and lower smoke across the full load range. The hard-coated plunger resists wear from today's low-sulfur diesel, extending service life between overhauls.

Two power variants available: 249-0709/10R-1273 (standard flow, EPA-compliant models) and 249-0702/10R-3261 (high-flow, +40 HP upgrade). Ideal for Class 8 trucks, 385C/390D-class excavators and heavy equipment. Always verify fitment by engine serial number (ESN) before ordering.
